IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 198,680, dated December25, 1877 application filed November 17, 1877.

To all whom it may concern:

Be it known that I, GEORGE W. PUTNAM, of Glens Falls, in the county ofWarren and in the State of New York, have invented certain new anduseful Improvements in Gar-Couplings; and do hereby declare that thefollowing is a full, clear, and exact description thereof, reference,being had to the accompanying drawings, and to the letters of referencemarked thereon, making part of this specification.

The nature of my invention consists in the construction and arrangementof a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled, in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure l is a longitudinal vertical section.

of my car-coupling, and Fig. 2 is a plan view of the same.

A represents the draw-head, with the usual flaring mouth B and interiorchamber 0. Dis the coupling-pin, provided near its upper endwithprojecting journals ortrunnions aa, which are insertedin enlargedholes b b formed in the jaws of a forked arm, E. This arm is pivoted ina sort of three-sided box, H, formed on or attached to the top of thedraw-head.

The arm E prevents the pin from becoming lost at any time, and also aidsthe pin in going down through the head in coupling the ears. I

d is the hole in the top of the draw-head for the passage of the pin'1), andv d is the correspondin g hole in the bottom of the drawhead.This latter hole d is made elongated sufficiently for the end of thecoupling-pin to pass into the same as it comes down on a curve by reasonof the arm E. This curve is, however, reduced to the minimum by thetrunnions a being placed in the elongated holes b in the fork of the armE.

In front of the hole 01 in the top of the draw-head is a step, as, forthe pin to rest in afteruncoupling. When it is desired to couple thecars the pin is placed in a step, y, in rear shown, it is made tosurround a guide-pin, z,

projecting rearward from the block. In addt tion to this a headed pin,m, projects from the under side of the block through a Iongi tudinalslot, n, in the bottom of the drawhead.

The fi'ont of the sliding block G is made beveled from the top downwardand rearward,

so as to overhang the inner end of the coup ling-link I, and thus holdthe same in a horizontal position for easy entry into the oppositedraw-head.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The box H, pivoted forked arm E, with slots b in its jaws, and the pinD, with trun nions a a, in combination with the draw-head 1 A, havingpin-hole d, with steps as 51 formed in front and rear at the top of saidpin-hole, substantially as and for the purposes herein set forth.

In testimony that I claim-the foregoing I have hereunto set my hand'this22d day of October, 1877.

GEORGE w. PUTNAM.
